Thanks everyone.

I just looked at the custard packet, its got 110 and 102 in it, both nasties. Urgh.

I had been making egg yolk custard, just had a momentary lapse of laziness... but will definitely go back to that now. I'm pretty sure she's OK with dairy as she has always had a lot of cheese sauce, yoghurt, & other stuff made with milk, and sleep never used to be so bad as this dreadful custard period.

This is such an eye opener!
